If a stream or channel is flowing at a rate of one cusec (cubic foot per second), what volume of water would flow through that channel in one hour?

✅Explanation:
A cusec (cubic foot per second) represents the flow rate of one cubic foot of water per second. To calculate the total volume of water that flows through a channel in one hour, we need to multiply the flow rate (in cusecs) by the number of seconds in one hour.
1 hour = 60 minutes × 60 seconds = 3600 seconds

• So, the volume of water flowing through the channel in one hour at 1 cusec is:
1 cusec×3600 seconds=3600 cubic feet

• To express this volume in millions of cubic feet:
3600 cubic feet=3.6 million cubic feet

🔑Key Points:
-Cusec is the measure of the rate of flow.
-It is still used by the department of irrigation.
-One cusec is one cubic foot of water flow per second.
-Approximately one cusec water is equal to 28.317 liters per second.
-7.48 gallons of water flowing each second is equivalent to one cusec.
